Functional Activation of G-Proteins Coupled With Muscarinic Acetylcholine Receptors in Rat Brain Membranes

open access: yesJournal of Pharmacological Sciences, 2014
.: The functional activation of Gi/o proteins coupled to muscarinic acetylcholine receptors (mAChRs) was investigated with the conventional guanosine-5′-O-(3-[35S]thio)triphosphate ([35S]GTPγS) binding assay in rat brain membranes.

Regulation of Src Family Tyrosine Kinases in the Rat Striatum by Muscarinic Acetylcholine Receptors [PDF]

open access: yes, 2017
Acetylcholine is an important neurotransmitter in the mammalian brain. This transmitter binds to muscarinic acetylcholine receptors (mAChR) to regulate activity of a variety of intracellular signaling molecules.

Modulation of c-Jun NH2-Terminal (JNK) by Cholinergic Autoantibodies from Patients with Sjögren’s Syndrome [PDF]

open access: yes, 2011
Background: We wanted to determine (via an immunopharmacological approach) whether the c-Jun NH2 terminal kinase (JNK) cascade is phosphorylated in the submandibular gland by carbachol and cholinergic autoantibodies (IgG) present in the sera of patients ...

The Possible Mechanistic Basis of Individual Susceptibility to Spike Protein Injury

open access: yesAdvances in Virology, Volume 2025, Issue 1, 2025.
Injury from spike protein, whether induced by COVID‐19 infection or vaccination, constitutes a significant health concern for numerous individuals. Considerable heterogeneity exists in individual responses to both COVID‐19 infection and vaccination, despite the latter being principally more controlled and consistent than the wide variety of infection ...

The Fatal Mushroom Neurotoxin Muscarine is Released from a Harmless Phosphorylated Precursor upon Cellular Injury

open access: yesAngewandte Chemie International Edition, Volume 63, Issue 52, December 20, 2024.
l‐(+)‐Muscarine is one of the most toxic mushroom metabolites. We identified its congener 4’‐phosphomuscarine in the fool's funnel and in various fiber cap mushrooms, and chemically and pharmacologically characterized this new natural product. As hydrolysis of its ester releases muscarine, our results help estimate the true toxin content of these ...

Muscarinic Receptor Subtypes Mediating Positive and Negative Inotropy in the Developing Chick Ventricle

open access: yesJournal of Pharmacological Sciences, 2007
The inotropic response to muscarinic receptor stimulation of isolated chick ventricular myocardium was examined at various developmental stages, and the receptor subtype involved was pharmacologically characterized.

Striatal and nigral muscarinic type 1 and type 4 receptors modulate levodopa-induced dyskinesia and striato-nigral pathway activation in 6-hydroxydopamine hemilesioned rats

open access: yesNeurobiology of Disease, 2020
Acetylcholine muscarinic receptors (mAChRs) contribute to both the facilitation and inhibition of levodopa-induced dyskinesia operated by striatal cholinergic interneurons, although the receptor subtypes involved remain elusive.

Ligand-guided homology modeling drives identification of novel histamine H3 receptor ligands [PDF]

open access: yes, 2019
In this study, we report a ligand-guided homology modeling approach allowing the analysis of relevant binding site residue conformations and the identification of two novel histamine H3 receptor ligands with binding affinity in the nanomolar range.

Advancing Neural Networks: Innovations and Impacts on Energy Consumption

open access: yesAdvanced Electronic Materials, Volume 10, Issue 12, December 2024.
A comparative study of ANN and SNN including biological neural networks is presented. An inefficiency of 5–8 orders of magnitude is indicated for modern ANN approaches, with the worst Transformer ANN over CPU. The most efficient implementation of the SNNs is biological neurons with only 100 fJ per synaptic weight update, next is inorganic Mosaic ...
